Transcranial Magnetic Stimulation and Perioperative Neurocognitive Disorders

"The rTMS mode consists of a cluster stimulus delivered every 0.2 seconds (5 Hz), with each cluster stimulus consisting of three burst stimuli with a 50 Hz body frequency. The duration of a single stimulus was approximately 40 seconds, for a total of 600 pulses. Stimulation takes place bilaterally in the dorsolateral prefrontal cortex (DLPFC).~All enrolled patient in the rTMS group will receive 1 set simulation per day with an intersession interval (ISI) of over 30 minutes on postoperative day 1 to 5 after the surgery."

Shaman stimulation uses the same protocol (600 pulses per session, 3 sessions per set, ISI≥30 min, 3 sets) with the coil set at 90 against the skull on postoperative day 1 to 5 after the surgery.
